J. M'. HURD, or AUBURN, NEW Youre MACHINE FOFty MAKING FLOUR-SAQKS.

Specification forming part of Letters Patent No. 43,773, dated August 9, 1864.

To all u'hoinit may concern:

Be it known thatI, J. lvI. HURD, of the city of Auburn, in Cayuga county and State of New York, have invented a new and. useful Machine for the Manufacture of Flour-Sacks; and I do hereby declare that-the following is a full, clear, and exact description of the saine, y

reference being had to the accompanying drawings, and to the letters of reference marked thereon. The object of this invention is for the purpose of facilitating the folding in of the lower corners ot the common square-bottom sack, so as to relieve the same from the objection to which that is liable. In the accompanying drawings the full machine is represented with all its parts in proper place, with a sack drawn over the top thereof, and shown in dotted lines, the bottom of the sack lying dat on the two leaves -A and B, with the corners vprojecting and terminating at C and D. The leaves A and B are jointed to the upright E and F at G and H. The two con` necting-rods I and J, the upper parts of which are shown in dotted lines, are jointed to the leaves A and B, the rod I to the leaf A, and the rod J to the lea-f B, and both rods are jointed to the levers K and l'i. lhe lever l( thereto by a piu, (shown at M,) which passes through both the post E and lever K.

Now, the operation of the machine is this: When the sack is placed upn the two leaves, as above described, the triangular pieces represented at N O G and P D Q. are pasted on the outer edges, and folded over onto and occupy the space included in the triangular spaces N U R and P Q S, and ywhile held in that position by the hand the feet are placed upon the treadle K, and the two leaves A and B are caused to close together, 'and the sack 'is raised for the stand complete.

Having thus described the construction and operation of my invention, what I wish-to secure by Letters Patent is- 1. The two leaves A and B, or their equivalents, substantially as and for the purpose specified.

2. The combination ot' the two leaves A and B with the lever K, substantially as above specified.

-J. M. HURD.
